a ci-tizen'of theUnited [States residing at Cleveland; in' 'the county o'f;, Cuyahoga and State of Ohio, have invented a new and usean Electric-Light-Globe H l e of whi h thefjfol lowingi's asp'eoificationa I The; presentinvention relates to light ng fixtures, and has more particular reference to lamps, globes and the. like. a

' The object of this invention is, to facilitats, the releasing. and replacing of, glass employed for detachably holding globes upon electric light sockets and the '1, .l ikefand to eliminate the uselof. set screws and other relatively rigid fastening devices the globesin place. -l

iigAnother ob eot of the. invention is to proa holderwhich may be readily attached in any- .-well. known. manner to the socket of anelectric lightfixture, and to provide the or otherwise damaging the same.

wherein:

Figure 1 is a fragmentary vertical secdesignates a globe of any desired configuration, and which has at its upper reduced end an outstanding annular bead 12 with a groove 13 in itv under side.

Fitted to the lower end of the socket 10 is a ferrule 14 of sheet metal or the like which is split in the usual manner and provided with a groove to engage the outstand- A holder 15,

.,S 1 1pported upon' the holder 15, and arranged at the. periphery thc'i'eofa-nd spaced apart substantially 120 degrees, are a" lu- Each spring clip isfornied of a singlelengthof strap metal having a flap attaching end 18 adapted tolie against the upper surface of the plate 15 and held thereto by overturned-lugs 19 stann' edfronrthe plate. Theend 18'of' the clip may be secured to the lugs by welding of the like, or the frictional contact-bf, the parts incident to the overturning'ofthe lugs may be relied upon. The end 18-[of-th'e strip constitutes the'base or supporting endthereof. -Adja cent the end i '18, the'stri'p is provided uith an upwardl'v andioutwardly looped portion 20-andtlic Est-rip extends down from the loop against .the outerflside of the flange 17 and is curved inwardly beneath the flange, and extends beyond the same where the strip is turned up to a slight extent to form a hook 21 adapted to engage beneath the bead 12 and in the groove 13.

The strip is curved downward and outward from the bill of the hook 21 to form a releasing finger 22 which is preferably curved sufficiently outward to space the finger from the globe when the latter is in place and to bear against the bead 12 as the globe is forced upward into the holder. The lower extremity of the strip is preferably overturned to form a smooth end to the finger. The strip is of resilient metal and of sufficient strength to support the globe.

In applying the globe to the holder it is only necessary to force the globe upward against the fingers 22 of the clips. The fingers are sprung outward by virtue of the spring loops 20, and the .bills of the hooks 21 ride over the bead 12 and admit the same beneath the flange 17. As soon as the bead 12 is in place the spring clips snap into normal position with the hooks 21 engaging about the bead 12 and in the groove 13 thereof. By providing the groove the hooks 21 are held from springing outward under the weight of the globe 11 and expansion or irregularities'in the thickness of the head 12 is taken up by the loops 20 without injury to the parts.

To release the globe it is only necessary to spring the fingers 22 outward from one or more sides of the globe for removing the hooks -21 from interlocking engagement with the bead 1'2. The "lobe 11 is now free to drop from the liglder. The depending straight portions of the clips which bear against the outer side of the flange 17 serve as means for retaining the hooks 21 in proper position and for holding the fingers 22 in position to receive the bead 12 thereagainst when the globe is forced into the holder.

\Vhat is claimed is:

1. In an electric light globe holder, the combination of a plate provided with a central socket receiving opening, and a flange surrounding said opening, said flange provided with threads for connecting the plates to a light socket, 11' dependin flange formed about the outer edge of sai plate, a lobe having an annular bead adapted to t in the flange, said bead provided with an undercut groove, and spring clips carried by the plate for detachably molding the globe in p ace, each of said strips rovided with flat portions lying in facial amtment with said plate, the en s of said flat ortions being bent and extending throug the plate, and tongues struck from the plate and engaging over said flat portions one upon each side, for coaction with said angled end to securely anchor the spring clips to said plate.

2. In an electric light globe holder, the combination of a plate provided with a central socket, receiving opening, and a flange surrounding said oiening, said flange proided with threads or connecting the plates to a light socket, a dependin flange formed about the outer edge of saic plate, a globe having-an annular bead adapted to in the flange, said bead provided with an undercut groove, and SPIIIIO clips carried by the plate for detachably holdm'g the globe in p ace, each of said strips provided with flat portions lying in facial abutment with said plate, the ends of said flat ortions being bent and extending througi the plate, and tongues struck from the plate and engaging over said. flat portions one upon each side, tor coaction with said anglec end to securely anchor the spring clips to said plate, each of said spring clips provided with an inturned upwardly curving hook intermediate its ends for engagement with the bead of said globe and seated in said roove. the in ermediate portion of the clip Being looped outward to increase the resiliency thereof and admit the springing out- \vardly of the hook to freely escape said bead.
